Application filed November 21, 1924. Serial No. 751,330.

This invention contemplates the provision of a pea grading machine, whereinthe peas are delivered onto an endless conveyorand carried thereby into a bincompartment-and wherein the whole peas are separated from the mashed or broken peas, and received by different receptacles arranged to communicate with said compartment.

The nature and advantages of the inventionwill be better understood when the following detailed description is read in connection with the accompanying drawings, the invention residing 1n the construction,

combination and arrangement of parts as claimed.

In the drawings forming part of this application, like numerals of reference indicate similar parts in the several views, and

wherein:

Figure 1 is a side elevation of the machlne constructed in accordance with the present invention.

Figure 2 is a topplan view partly in section. I

Figure 3 is an end View partly in section. Figure 4 is a fragmentary vertical sectional view through the bin, showing the arrangement of parts utilized for separating the peas.

Figure 5 is a fragmentary front end elevation of the machine.

Figure 6 is a detail sectional view showing how one of the rollers is mounted for adjustment.

The machine forming the subject matter of. this invention comprises a bin indicated at 10 and adapted to bemounted on a suit able frame-like supporting structure indi-' cated generally at 11. The bin 10 is divided by a short vertically disposed partition 12- into the compartments 13 and 14' which of course communicate above the partition 12 as clearly illustrated in Figure 4. ,Arranged to operate within the bin is endless belt 15, the belt being trained over spaced rollers 17 and 18 respectively, the'roller 17 being journalled within the bin directly above and slightly in advance of the; partition 12 to bring that end of the conveyor 15 into the compartment 14 for a purpose to be pres ently described. The shaft 19 of the roller 18 projects an appreciable distance beyond one sideof the machine, and has associated therewith a belt pulley 20 over which is trained apower belt 21, the machine being operated by any suitable motive power as 'ment 30 is bottom. 1 After the peas have. been deposited on'the the slack n the belt 14, and for this purpose use is made of a pair ofadjustingscrews'23 jmounted at the opposite sides of the machine and associated with the brackets 24, whereby the rollercan be easily and conveniently adjusted within said slots. The adjusting screws are equipped with handles-'25.

, Mounted upon the supporting structure, immediately above the roller 18 is ahopper 26 which is adapted to receive the peas, and feed thesame onto theendless conveyor 15.

The hopper is provided with a'sliding doorv 27 at the front thereof, which can be opened to any degree, to regulate or control the flow peas fromthe hopper onto the endless belt. The door canbe held in any given position by means of a pin'28 adapted to be received by any one of a plurality of openings29 as'clearly shown in Figures, 1 and 5. Arranged to reciprocate across the bottom of said hopper is an agitating element 30, and this element is connected with one end of a link 31 which has itsother end eccentrically connected with a disk 32 supported by the adjacent end of a vertically disposed r shaft 33 whichis mounted in suitable bearings at o e side. of the c ne sc y shown in Figure 5. The lower end of this shaft 33 carries abevel gear34 which meshes -with .a similangear 35 carried by a stud shaft 36 which is mounted for rotation upon the supporting structure,- and projecting lae erally therefrom. This shaft 36 also supports a sprocket; 3,7, and trained over this sprocket and a similar sprocket 38' fixed upon the'shaft 19 of. the roller 18 is a drive chain. 39. Manifestly, the shaft 26 is r otated from the shaft 19, and rotary motion imparted to the shaft 33 from the shaft 36. As the shaft 33 is rotated, the agitating elereciprocated across the hopper conveyor 15, they .are carried into the compartment, 14,- wherein the whole peas are separated from the mashed or broken peas in the manner clearlyillustrated in Figure 4. For thispurpose I employ a'pa'ir of spaced parallelmembers 40and' 41 respectively which are arranged vertically and extended transversely across the compartment 14, These members are arranged immedipursued by the shelf 49, and bounce from this shelf direction of the outlet opening 45.

ately adjacent the endless conveyor 15, with the member 40 extending upwardly to terminate substantially in a plane with the upper run of the conveyor as shown in Figure 4. Projecting forwardly from the mem ber 40 is a horizontally disposed shelf42 which is slightly inclined downwardly as shown in Figure 4, and of a suflicientsize to serve the purpose intended. As the peas leave the endless conveyor 15, the whole peas pass over the member 40 onto theshelf 42, and bouncetherefrom against the partition 43 which is arranged adjacent the forward ceptacle is adapted to be arranged to receive said peas. Now, should any of the whole peas, upon leaving the endless conveyor 15 strike the member 40 and pass downwardly through ,thespace between the members 40 and 41 respectively, which course is to be mashed and broken peas, the whole peasupon striking the shelf 46 are again bounced therefrom over the member 47 striking the curtain 44 and then falling through the opening 45 to their proper destination. Arranged beneath the shelf 46 are spaced parallel members 47 and 48 respectively which are arranged to extend transversely across the compartment 14, the space between these members defining a passage through which the mashed or broken peas are adapted to pass, as they find their way to the bottom of the compartment. It

willbe noted that the member 47 terminates substantially in a plane to the upper surface of theshelf 46 to act as a stop for the peas as they roll ofi the shelf 46 and thus direct the said peas through the passage just referred to. In event that some of the whole peas should again pass between the members 47 and 48, they would fall upon another in a mashed or broken peas continue to roll off each shelf as they are brought in contact therewith, and fall througha restricted passage until they reachthe final outlet passage 50 defined by a pair of spaced parallel members 41 and 42 respectively which are arranged transversely of the compartment 14.

A suitable receptacle not shown is adapted to be arranged beneath these members 51 and-52 to receive the mashed and broken peas as they ultimately pass from the compartment 14. It will be noted upon inspection of l igure 4 that the different pairs of spacedfparallel members are arranged in staggeredrelation, thereby causing the mashed and broken peas to pursue an ir- The 7 peas will strike the curtain 44 and'be directed. downwardly through the outlet opening 45.,

It will be noted upon inspection of Figure 1 that the membersof each pair of spaced parallel members are susceptible of vertical adjustment by slot and pin connections 53, and that each shelf above referred to is susceptible of horizontal adjustment by a slot and pin connection 54 with their respective supports 55; Furthermore, the roller 17 has a shaft journalled inbearings 56 -which are also susceptible of adjustment vertically through slots 57 thusmaking it possible to change the degree of angularity ofinclination of the endless conveyor. l

Arranged transversely within the compartment 13 of the bin is a transverse strip 58 of any suitable material which is arranged to contact the lower run of the endless conveyor as shown in F igurel, and this strip not only serves to support. the lower run of said conveyor, butis also utilized to scrape the conveyor, to remove dirt and other foreign matter therefrom, and thus maintain the. conveyor in a clean condition. Mounted on the supporting structure 11 directly beneath the transverse element 58 is a receptacle 56 Which is adapted to receive this dirt and foreign matter as it is sepa-.

rated from the conveyor.

While it is believed that from the forelimit myselfto whatis herein shown and described, and that such changes may-be resorted to when desired as fall withinthe scope of what is claimed.

Having thus described the invention, I

claim: i

A machine of the character described comprising a supporting structure, a bin mounted thereon, a partition dividing the bin into two compartments, an endless conveyor disposed at an inclination above one of said compartments with one end arranged above the partition and extending into the other of said compartments, ahopper mounted above the opposite end of said conveyor, pea grading means arranged infithe last mentioned compartment, a receptacle mounted for disposal in the other compartment,

and scraping means arranged in the pathof the conveyor and above the receptacle.

2.
